Description

Bicycle Helmet

The invention relates to a bicycle helmet having a casing and a goggle, wherein the casing has an arch-shaped accommodation space between the outside and the inside thereof, and the goggles are movably received in the accommodation space and Can be moved between the open position and the under-cover position. The goggles include a protection portion and a holding portion having an operating member on the upper side. The casing has an operation channel on its outer side, which extends in a radial direction (arched with respect to the accommodation space) to the accommodation space of the casing, wherein the operating member of the goggles is engaged in the operation channel, Thereby, it abuts on the outer side of the casing, so that the goggles can be displaced between the opened position and the position under the cover.

In such bicycle helmets, at least the protective part of the goggles is transparent, and the goggles provide protection for the eyes of the wearer of the bicycle helmet in a position under the cover, for example, to prevent airflow, falling objects, dust particles or insect. In order to be able to serve as anti-light, the goggles can be added with color or can be equipped with another filter. If the user of the bicycle helmet does not need or does not want the goggles (for example, during transportation or storage of the bicycle helmet), the goggles can be moved to the open position by the operating member, and In the open position, the protective part of the goggles is at least partially Move to the receiving space of the helmet shell.

Some users desire to be able to change the goggles, for example, to choose to use goggles with or without sun protection, or to replace damaged goggles.

The types of bicycle helmets are known, for example, EP2548462A1 and EP2689680A2. The bicycle helmets described in these patents include replaceable goggles. In order to replace the goggles, first, the operating part of the goggles must be separated from the goggles so that the goggles can be completely removed from the helmet. . After inserting the same goggles or new goggles, the operating member must be fixed to the goggles again. Some users regard this as difficult because during the assembly process, it is not easy to see the goggles used to fix the fixing part of the operating member through the operation channel.

Therefore, the object of the present invention is to provide a bicycle helmet with goggles, which has a simple and stable design and simplifies the replacement of the goggles.

In order to meet this objective, a bicycle helmet having the features of the first item of patent application scope is adopted. Specifically, the casing has a guide channel on its inner side, and the guide channel extends to the inner and outer sides. Accommodation space between. The guide channel extends to and communicates with the front side edge of the casing (that is, the front side edge of the casing).

The guide channel extends from the inside of the helmet shell to the receiving space (specifically, toward the receiving space or the head). Helmet housing arched radial). The guide channel is extended to the front side edge of the helmet shell (specifically, toward the longitudinal direction of the bicycle helmet). Specifically, the guide channel and the operation channel of the helmet shell can be along the bicycle helmet. Common extends longitudinally. However, the guide channel can be wider than the operation channel. Preferably, at least the width of the guide channel corresponds to the width of the holding portion of the goggles, at least the front edge of the guide channel, that is, at least the area of the front edge of the helmet shell.

Because the guide channel communicates with the front side edge of the casing, the holding portion (including the operating member) of the goggles can be introduced into the accommodation space or into the inner channel of the helmet casing. Therefore, for the replacement of the goggles, the holding part of the goggles can be inserted or placed in the guide channel (specifically, in the radial direction opposite to the arch shape of the helmet shell), and is provided in the goggles From this position, the operating member on the holding part can be introduced into the operating channel. For this purpose, preferably, the operating member moves in the direction of the outer side of the helmet shell, and at the same time, it can provide the holding part of the goggles to move in the longitudinal direction (that is, along the accommodation gap).

The restriction can be selectively made: for the holding part of the goggles to be introduced into the accommodation gap, or for the operation member to be inserted into the operation channel, the operation member itself and / or part of the helmet shell is temporarily slightly elastically bent.

The goggles can also be selectively guided individually by the guide channel, as will be explained in more detail.

A bicycle helmet, especially the bicycle helmet of the present invention, generally has a concave arched inner side and an upward convex arched outer side. This is to make the terms "outside" and "inside" of the present invention correspond to the arched surface. The description of the position and orientation of the present invention normally refers to the placement of the bicycle helmet on the wearer's head according to its intended use. For example, the term "front side" means that the bicycle helmet is located on the user's forehead area and therefore faces one side of the user's gaze direction, and the term "back side" refers to the bicycle helmet provided on the wearer's head The area behind the neck is thus turned away from one side of the wearer's gaze direction. The "longitudinal" should be understood as a direction extending between the front and rear sides of the bicycle helmet.

The opened position of the goggles corresponds to the "up position", in which the retaining portion of the goggles is completely accommodated in the accommodation gap of the housing, and the protective portion is mostly or completely accommodated in the The housing is contained in the gap. On the contrary, the position under the cover of the goggles corresponds to the “down position”, in which the retaining portion is mostly or completely accommodated in the accommodation gap of the casing, but the protecting portion is mostly or completely Move out of the accommodation gap of the casing.

Preferably, according to the arch shape of the accommodation space, the goggles can be bent to be easily accommodated in the accommodation space. Preferably, the holding part of the goggles is extendable and protrudes from the protection part toward the longitudinal direction of the bicycle helmet. An operating member of the goggles protrudes from an upper side of the holding portion.

Preferably, at least the protective part of the goggles is transparent, so that the user of the bicycle helmet can serve as a transparent protective windshield. For example, weather-induced landings, such as raindrops or snow particles, can isolate the eyes of the user of the bicycle helmet by the protective part of the goggles, so that even in harsh weather, the sight and visibility can be minimized Degree reduction. The protective part of the goggles may further have properties of commercial sunglasses, such as painting. Techniques such as ultraviolet absorption and / or light reflection can also be specifically provided on the protective portion. Depending on personal needs or the aesthetics of the user, different goggles can be provided on the helmet. Therefore, the purpose of the simple replacement function of the goggles expected by the present invention is a special advantage for the user, for example, because the goggles can be quickly replaced without being complicated according to the current weather conditions.

The shell of the helmet can have a dome with a shock-absorbing material, for example, expanded polystyrene foam (EPS). The casing has a polyvinyl chloride (PVC), polyethylene terephthalate (PET), polycarbonate (PC) or acrylonitrile-butadiene-styrene (ABS) outer casing. Exhaust holes can be provided on the outer shell and the vault, preferably, they are arranged in alignment with each other to ensure that the user's head surrounded by the bicycle helmet maintains particularly effective ventilation.

Preferred embodiments of the present invention are described below and in the appended items.

In a preferred embodiment, the guide channel at least partially overlaps the outer operation channel. Understandably, at least a part of the inner guide channel overlaps with the outer operation channel, so that the arrangement of the guide channel is at least partially aligned with the operation channel. Preferably, a through-opening between the inner side and the outer side of the casing is formed on the overlapping area of the guide channel and the operation channel. For the goggles to be connected to the helmet shell, in the area of the through-opening, the operating member provided on the holding portion of the goggles can be simply inserted into the operating channel from the inside of the bicycle helmet (specifically Ground, in the position under the cover of the goggles). However, this overlap is not absolutely necessary, especially when the operating member is elastically compressible, which will be described later.

In another embodiment, the guide channel and the operating channel of the housing overlap a distance along a corresponding longitudinal section thereof, and the distance corresponds to at least the length of the operating member of the goggles. Thereby, the operation member can be simply inserted into the front side section of the operation channel from the inside of the bicycle helmet.

In a preferred embodiment, the guide channel of the housing is widened relative to the front side section of the rear side section, wherein the width of the guide channel at the front side section corresponds at least to the width of the holding portion of the goggles. In addition, the width of the guide channel at the rear section is smaller than the width of the holding portion of the goggles. Preferably, the overlapping area (when present) of the guide channel and the operation channel is located on the widened front side section of the guide channel. Therefore, the holding part of the goggles can be introduced into the accommodation gap along the widened area. The lateral boundary of the guide channel on the rear side section can be fitted next to the holding portion, thereby ensuring good guidance of the holding portion and defining the displacement of the goggles along the longitudinal direction.

In another preferred embodiment, the bicycle helmet has a closure member on an area of the front side edge of the casing, which is detachably fixed to the inner side of the casing to close the guide channel. After the previously-mentioned operating member is inserted into the operating channel, and preferably, after the holding portion of the goggles has at least partially entered the receiving space of the helmet shell, the closure member can be connected to the helmet shell The front side edge closes the front side edge of the helmet shell, thereby blocking the goggles from undesirably leaving the accommodation gap of the helmet shell. In contrast, in order to selectively separate the goggles from the helmet shell, The process is performed in the reverse order, that is, first, the closure member is removed from the front side edge of the housing, and then the operating member of the goggles is moved inward, and thus the outer operating channel is removed. Finally, the The goggles can be pulled forward to completely move out of the receiving space of the helmet gap. Since the closures for the guide channel and the notches required for this are provided inside the helmet shell, the housing system is quite robust.

In a preferred embodiment, the closure member can be inserted into the guide channel of the housing by a force fit and / or a shape fit. For example, the plug-in closure can be held in place in a clamped or snap-fit manner. Alternatively, additional fixings can also be provided between the closure and the housing (for example, at least one screw, at least a pair of hook and loop fixing assemblies, or displaceable bolts).

The closure can be formed from a flexible material. In particular, the closure member can be formed of an elastic material (that is, a material that can be rebounded). This feature becomes a particular advantage when the closure is retained on the guide channel of the housing in a sandwiched manner. When an engaging mechanism is provided to fix the closure, since a relatively small external force must be applied to secure and release the closure, the flexible material can be simplified or at least more suitable for making parts of the closure.

In another preferred development of the present invention, the holding portion of the goggles has a joint on its lower side, and the joint is engaged in the guide channel of the casing and in a position under the cover of the goggle. , The joint contacts the closure. Therefore, the engagement member and the closure member cooperate with each other, so that the closure member is defined to be engaged with the end of the goggles, and the engagement member of the goggles will engage against the end when reaching the position under the cover of the goggles. At this time, the goggles can be guided by engaging the engaging member in the guide channel, and The goggles are moved between the opened position and the under-cover position.

Preferably, the engaging member is molded as a single member or fixed on a holding portion of the goggles.

Regarding one of the embodiments of the closure member described below to define a variable end joint, the position of the goggles under the cover can be adjusted by the user, so that the goggles are particularly advantageous. Joint.

In a preferred embodiment, the closure member can be selectively fixed on the housing at at least a first positioning point or a second positioning point, so that the closure member is at the first positioning point and at the first positioning point. The two positioning points define different lengths of the guide channels. For the goggles in the position under the cover, it is possible to define the positions where at least two different ends are engaged. Specifically, the closure member can be inserted into the guide channel by being rotated 180 ° or 90 ° (for a maximum of four different positioning points) relative to the first positioning point (for two different positioning points). Therefore, with the variable length of the guide channel, the position under the cover of the goggles can match the eye or nose of the helmet user, so that in the position under the cover, the protective portion of the goggles is completely longitudinally Cover the eye area of the helmet user, but at this time will not abut the nose bridge of the helmet user. Due to the swaying movement of the bicycle helmet during travel, it is particularly necessary to avoid the abutment of the protective portion on the bridge of the nose, as they may cause pain to be applied to the skin of the nose. The eye area is still completely covered as expected, so that the protective part can effectively protect the eyes of the helmet user.

Alternatively or in addition, the closure has a recess on at least one end surface, and compared to the other end surface of the closure (specifically, the phase Compared with an end surface provided opposite to the aforementioned end surface), the recess defines a larger length of the guide channel. For example, the recess can be formed as a rectangular recess on the end face of the closure member to engage the aforementioned goggles' engaging members in a position under the cover of the goggles. Therefore, in the under-cover position, the engaging member and the goggles are kept in a relatively suitable position by the sides of the recess, thereby avoiding disturbing swinging movements of the goggles, for example, the bicycle is irregular The surface travels. Moreover, the width of the recess can be slightly smaller than the width of the joint. Thereby, the engaging member that engages the recessed portion is held in the recessed portion by the clamping method (under the cover position), and by the manual operation of the operating member of the goggles, the engaging member that engages the recessed portion is only removed from the cover. The position is shifted toward the opened position. In addition, in the displacement of the goggles from the open position to the cover position to produce a clamped state, it is necessary to use a suitable manner and the goggles' engaging members will not suddenly engage the closing members, so the effect is slightly increased. The means of force is necessary to indicate to the user of the bicycle helmet that the position under the cover has arrived. In this regard, the use of a flexible material for the closure can facilitate the development of the aforementioned features.

In another embodiment, the closure has at least one predetermined breaking point or tangent point that can be selectively matched to provide additional or added recesses on the closure by breaking or cutting the closure. A predetermined portion to increase the length of the guide channel for the above-mentioned joint. Thereby, the user of the bicycle helmet can increase the length of the guide channel in a simple manner, so that the position under the cover of the goggles is suitable for personal needs.

Alternatively or additionally, in order to make it possible to adjust the length of the guide channel, in another preferred embodiment, the closure can be The casing is selectively fixed at at least a first longitudinal position or a second longitudinal position, so that the closure member defines a different length of the guide channel at the first longitudinal position and the second longitudinal position. Therefore, the closure can be fixed to at least two different longitudinal positions on the helmet shell.

Another alternative includes providing a combination of a plurality of closures to the user of the bicycle helmet, and each of the closures defines a different position of the end engagement for the engagement member. For example, in each of the closure members, the recessed portions used as the engaging members can have different lengths. With various choices of the closure member, the length of the guide channel can be changed correspondingly.

In another preferred embodiment, the housing includes a dome and an insert. The vault has a vacant area on its inner side, wherein the insert is inserted into the vault and is permanently fixed on the vault. The guide channel is formed on the insert. The receiving space is formed between the vault and the insert. Because the accommodation gap is formed in a simple manner by the distance between the insert that has been inserted into the vacant area and the vault, the use of a separate insert simplifies the production of the helmet. Both the vault and the insert can be formed of shock-absorbing materials, and in particular both are formed of the same material.

In another embodiment, the operating member is elastically compressible, for example, it is formed of foam or serves as a spring portion. Specifically, due to this feature, the overlap of the guide channel and the operation channel can be omitted, and the operation member can be compressed on the guide that the goggles (and the holding portion) enter the accommodation space. Until reaching the operation channel. After reaching the operation channel, the operation member expands therein and automatically engages it. Due to the radial boundary of the accommodation gap, the compression occurs approximately in the radial direction (phase For the arch of the accommodation gap). In contrast, the operating member is compressed from the outside (through the operating channel) to remove the goggles from the accommodation space. In this embodiment, because the front boundary of the operation channel defines the goggles and the ends that engage the operating members, the goggles will not accidentally fall out of the accommodation gap, so they can even be omitted entirely. Closures.

Preferably, the operation member is molded as a single member or fixed on the holding portion of the goggle, thereby avoiding an unexpected separation of the operation member from the holding portion of the goggle.

As shown in FIGS. 1 a, 1 b, and 2, a bicycle helmet 11 includes a housing 13 and transparent goggles 15. An arch-shaped accommodation space is formed between the inside and outside of the bicycle helmet 11, and the goggles 15 are movably received therein. In terms of structure, the accommodation gap 17 shown in this embodiment is formed between the dome 19 and the insert 21, and the insert 21 is inserted into the vacant area inside the dome 19 and is fixed there for a long time. The insert 21 is shown in detail in FIG. 4. In the figures 1a and 1b, the goggles 15 are located in the open position, so that the goggles 15 are fully guided into the accommodation space 17.

The guide channel 23 is formed on the insert 21; it faces in the radial direction (relative to the arch shape of the accommodation space 17 or the helmet housing 13). (Arch shape) extends outward from the inside of the helmet shell 13 to the receiving space 17, and it extends longitudinally to the front edge of the shell 13 and communicates there (Figure 1b). A plurality of ventilation holes 25 are provided on the casing 13 to facilitate ventilation of the head of the covered wearer during use of the bicycle helmet 11.

The goggles 15 are shown in detail in FIG. 3. It includes a tongue-shaped retaining portion 27 and a sheet-shaped protection portion 29, and the protection portion 29 is placed under the cover to protect the eyes of the wearer of the bicycle helmet 11. The operation member 31 is formed on the upper side of the holding portion 27. A bonding member 37 (shown by a dotted line in FIG. 3) is formed on the lower side of the holding portion 27. The goggles 15 are curved, and have a recessed portion 33 on the area of the protection portion 29, so that when the goggles 15 are located under the cover, the nose bridge of the helmet user fits over the recesses, such as Described later.

At the position under the cover of the goggles, at least the protection portion 29 is turned out of the accommodation space 17 as shown in FIG. 2. The holding portion 27 of the goggles 15 is received in the receiving space 17. An operation channel 35 that engages the operating member 31 of the goggles 15 is formed on the outside of the bicycle helmet 11 to allow manual operation to move the goggles 15 between the lifted position and the under-cover position (Figure 2). between. For this purpose, the operating channel 35 extends radially inwardly (toward the arch of the accommodation gap 17 or the arch of the helmet shell 13) from the outside of the helmet shell 13 to the accommodation gap 17. On the inner side, the engaging member 37 is formed on the holding portion 27 to be engaged in the guide channel 23 (FIGS. 1a and 1b). In Figure 1a, the closure is detachably fixed to the inside of the housing 13 (for example, by a clamping arrangement). Element 39 closes the front end of the guide channel 23, that is, the area of the front side edge of the casing 13. In Figure 1b, the closure 39 is removed. Specifically, as shown in FIG. 1 b, the guide channel 23 is widened toward the front side section adjacent to the edge of the shell 13 relative to the rear side section toward the center of the helmet. The width of the front side of the guide channel 23 corresponds to at least the width of the holding portion 27 of the goggles 15.

Specifically, in FIG. 5, the operation channel 35 can be viewed from below, which partially overlaps the guide channel 23, and the portion 49 of the overlapping area extends into the widened portion of the guide channel 23, And the portion 49 of the overlapping area has the length of the operation member 31.

A particular advantage of the illustrated bicycle helmet 11 is that the goggles 15 can be replaced in a simple manner.

For the installation of the goggles 15, after the closure 39 is removed from the helmet shell 13, the goggles 15 are placed in the inner side of the shell 13, and the holding portion 27 is along the guide channel 23. The front side section is located at the front, and the upper operation member 31 is engaged into the operation channel 35 of the housing 13. Then, the goggles 15 can be introduced into the accommodation gap 17 until the goggles 15 are completely contained in the accommodation gap 17. In this regard, the operation member 31 is engaged in the operation channel 35, and the engagement member 37 is engaged in the guide channel 23. The closure 39 is then inserted into a wider portion of the guide channel 23, as shown in Fig. 1a. Therefore, the closing member 39 fixes the goggles 15 in the accommodating space 17, and at the same time, the joint 37 of the goggles 15 is defined in the forward direction (the opening position of the goggles 15), and the end joint is defined. .

The closing member 39 is detachably inserted into the guide channel 23 in. Therefore, the goggles 15 can be selectively removed again in the reverse order, for example, to replace the goggles 15 with a different goggle.

The partial view in FIG. 1b is shown in FIG. 5, and the protective portion 29 of the goggles 15 is almost completely turned out of the accommodation space 17. Specifically, FIG. 5 shows an enlarged view of a region of the guide channel 23 and a region of the operation channel 35, and a cover is shown by a dotted line. The lower perspective corresponds to the inside view of the helmet equivalent to Figure 1b. As already mentioned, the inner guide channel 23 at least partially overlaps the outer operation channel 35, that is, the guide channel 23 is arranged at least partially aligned on the outer operation channel 35. As described, for the installation of the goggles 15, the free end of the holding portion 27 of the goggles 15 having the upper side operating member 31 can be inserted into the portion 49 of the overlapping area of the widening of the guide channel 23. For this purpose, the width of the guide channel 23 in the front section (widening) is slightly larger than the width of the holding portion 27 of the goggles 15. The width of the guide channel 23 at the rear side is smaller than the width of the holding portion 27, that is, the lateral boundary of the guide channel 23 is fitted beside the holding portion 27. Here, what is not seen in the holding portion 27 is indicated by a dotted frame.

FIG. 6 a is a partial cross-sectional view of the bicycle helmet 11, and the cross section extends vertically through the guide channel 23 and the operation channel 35 in the longitudinal direction. As shown in FIG. 6a, the goggles 15 are located at a transition position between the opened position and the under cover position, the operating member 31 is engaged in the operating channel 35, and the engaging member 37 is engaged to the In the guide channel 23. As shown in FIG. 6a, a portion of the bicycle helmet 11 provided above the goggles 15 includes the vault 19 and an outer shell 41 except for the embodiment shown previously. As shown in Figure 6a, the bicycle helmet 11 is provided The portion below the goggles 15 is composed of the insert 21, the closure 39, and an optional inner liner 43.

Figure 6a shows an alternative embodiment. FIG. 6b roughly corresponds to FIG. 6a, but in this alternative embodiment, the operation channel 35 and the guide channel 23 do not overlap. Moreover, in Fig. 6b, a closing member 39 for inserting the guide channel 23 is not provided. In this embodiment, preferably, the operation member 31 is elastically compressible, so that, on the one hand, the holding portion 27 of the goggles 15 can be introduced into the accommodation gap 17, and on the other hand, the The introduced goggles 15 are fixed in the accommodation space 17. In other words, the operation member 31 is compressed in the longitudinal section 51 of the accommodation space 17, and the operation channel 35 and the guide channel 23 do not overlap here, and the operation member 31 reaches the operation channel 35 At this time, the operation member 31 is automatically engaged in the operation channel 35. Due to the radial boundary corresponding to the accommodation gap 17, the compression of the operating member 31 occurs approximately in the radial direction (relative to the arch shape of the accommodation gap 17). The boundaries are formed by the dome 19 and the insert 21, as shown in FIG. 6b.

Figures 7a, 7b and 7c show different embodiments of the closure 39. The closing member 39 shown in FIG. 7 a has a substantially rectangular recessed portion on the end surface, and the recessed portion forms a recess 45 for the joint member 37. In this regard, the depth of the recess defines the effective length of the guide channel 23 with the closure member 39 inserted (Figure 1a). In particular, the depth of the recessed portion also defines the position of the goggles 15, in which the engaging member 37 engages the recess 45 of the closing member 39, and the goggles 15 are turned out of the accommodation gap as much as possible ( Under cover position). The closure 39 can choose between two different anchor points One of them is fixed to the helmet shell 13, that is, one of the end face of the closing member 39 with the depression 45 or the oppositely disposed end face faces the guide channel 23 to face the cover of the goggle 15 The lower position defines two different end joints.

Alternatively or in addition, the closing member 39 can be selectively inserted into the guide channel 23 at different positions in the longitudinal direction, thereby also changing the length of the guide channel.

With these feasible changes, in the position under the cover, the protective portion 29 of the goggles 15 is accurately arranged in front of the eye area of the helmet user, and the protective portion 29 will not abut against the helmet wearer Bridge of the nose.

The embodiment of the closure member 39 shown in Fig. 7b corresponds to Fig. 7a, and predetermined breaking points 47, 47 'are added to the closure member 39. For example, the predetermined breaking points 47, 47 'can be implemented by perforation. By destroying (e.g., by a screwdriver device) a portion of the closure member 39 defined by the predetermined breaking points 47, 47 ', the position of the depression 45 can be changed toward the center of the closure member 39. The range of rotation of the goggles 15 can thereby be increased, so that the protective portion 29 of the goggles 15 can turn more out of the accommodation gap 17 in the position under the cover. The feasible means of applying this change is that, in the position under the cover, the protection portion 29 is accurately arranged in front of the eye area of the user of the helmet.

FIG. 7c shows another embodiment of the closure member 39, that is, a relatively concave portion with a different depth is provided on the end surface. The recesses define the recesses 45, 45 ', but only one of them is used as the joint 37. Of the end joint. As shown in FIG. 7c, the closure member 39 can be rotated through 180 ° to selectively insert the guide channel 23. Here, the closing member 39 is fixed, and the recesses 45 and 45 'are used as the ends of the joining member 37 to be joined. Therefore, the position of the protection portion 29 can be changed in a particularly simple manner, and there is no additional appliance in the position under the cover of the goggles 15.
